But please check very carefully as the distance from the centre of the gudgeon pin to the edge of the piston may be slightly different so the squish clearance must be checked and the base gasket thickness adjusted to suit.

Beta Evo 250 2011 to 2022

On the Beta Techno, Rev 3 and Evo 250 using this S3 piston will very slightly lower the compression, this can easily be compensated for with the base gasket thickness.
